Israel's concern about being dragged before the international courts is unfounded by Jay Knott (12/06/12) ⇌ (Freedom)
"One of the reasons Israel objected so vehemently to the premature UN recognition of Palestine as a state was the apprehension that the International Criminal Court at The Hague (ICC) would, subsequently, accede to a request by the “state of Palestine” to join the Court. Once accepted as a member state, the Palestinians might then attempt to have Israeli officials indicted."
Israel needn't worry about the international courts. They follow the politics of the major powers, charging those considered their enemies, and freeing their friends. They'd imprison the head of Hamas, and give a medal to the prime minister of Israel.
